DISH-WASHING MACHINE.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed June 1, 1814. serial in. 842,088.

To all whom it may concern.-

Be it known that I, URIAH HUTCHINSON, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in 'Dish- Washing Machines, of which the following is a specification, reference being had there in to the accompanying drawings, which form a part thereof.

My invention relates to dish washing machines and more particularly to;-a type of hand operated machines especially adapted for household use.

By my invention, I am enabled to produce a machine of small dimensions and suflito be conveniently handled in a kitchen, and one which may be operated with the expenditure of but little energy, the cleaning effect upon the dishes being secured by a swirling action of the cleaning fluid, or by means of a'current assing about the tank, as distinguished mm the mere agitation of the water or the forcing of the water upwardly from the bot-- tom of the tank as is done in a well known and common type of machine. A machine of this character must embody therein a water wheel or paddles for giving motion to the cleaning fluid and in conjunction therewith, I provide actuating means therefor, and a support for the dishes which will prevent the impact of any of the movable parts of the machine with the dishes in such manner as would have a tendency to chip or break the latter. I also so construct and arrange the various parts of the machine as to permit a large number of dishes to be 51- multaneously cleansed and to permit the dishes to be washed, scaldedand drained while in the machine.

My invention also contemplates a structure wherein after each use of the machine, the dish supporting and paddle wheel mechanism may be quickly removed from the tank to permit the thorough cleansing of all parts or the machine, and the removal of refuse from the bottom of the tank.

In producing a machine made in accord ance with my invention. I have so constructed, designed and combined the various parts that the machine will have a low cost of production, the tank thereof may be renewed at small cost in case of leakage from wear or rgst; and the paddle wheel and dish supporting mechanism will be rigid and durable.

My invention consists primarily in a. dish washing machine embodyin therein a tank for the washing fluid, a rigi frame, having a top bar extending across and engaging the edge of said tank whereby said frame may be removably mounted in said tank, and a bottom bar adjacent the bottom of said tank, a. rotatable shaft mounted in said top and said bottom bars, a plurality of paddle blades carried by said shaft, means whereby said blades are supported adjacent, but out of contact with the bottom of said tank, said paddles having vertically disposed bucket surfaces whereby the water will be swirled about the tank thereby, and a reticulated support for dishes mounted upon said frame above said paddle blades; and in such other novel features of construction and combination of parts as are hereinafter set forth and described and more particularly pointed out in. the claims hereto appended.

Referring to the drawings: Figure l is a vertical section of a dish washing machine embodying my invention; Fig. 2 is a plan View thereof with a portion of the reticulated dish support broken away; Fig. 3 is a view of the central portion of the water wheel or paddle blades, and Fig. 4 is a side elevation thereof broken away to'show the manner of connecting said blades to their actuating shaft. I

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, I employ an ordinary circular tank a preferably made of sheet metal, galvanized or tinned and provided with ordinary haudles a. Said tank has a drain opening a near the bottom thereof and cornmunicating therewith is a nipple a by means of which a. flexible tube may be connected .with said tank. to permit the convenient filling and draining of the tank. :1 use a flexible tube 1) so that direct connection with a hot water faucet may be made, thus eliminating the necessity for carrying water. l urthermore, by using such a tube, the tank may be set upon a drip board or lid to a stationary tub, and the water drained into an adjacent sink or tub.

Pendant from the edge of the tank a is a frame by means of which the water wheel or paddle blades are supported adjacent to and out of contact with the bottom of, and the support for the dishes is mounted within,

said tank. This frame preferably is rectangular and is made of a fiat strip of iron or ther metal of the desired strength. It con- .sists of a top bar a, the ends of which extend across the top edge of said tank a, the parallel bottom bar d and side bars ef pref erably formed integrally with said bottom bar and having the ends thereof turned-outwardly at ef' to permit the top bar 0 to be connected therewith, said turned ends forming with the ends of the bare, laterally extended lugs for sustaining the load upon and preventing the turning of, said frame. through engagement with the walls of slots aa formed at the top of said tank a. Carried by the bottom bar d are cross bars qg the purpose of which is to aitord an extended rest for the reticulated dish support h and thus not only prevent possible sagging of said support under its load but the tilting thereof as well. The support h is of fairly heavy gage wire screening of a sufficiently small mesh and extending into sufficiently close juxtaposition to the wall of the tank a to prevent table silver escaping partially therethrough and obstructing the water wheel or paddle blades. Extending between the top bar 0 and the bottom bar d is a tubular bearing i the opposite endspf which are secured to said bars respectively and mounted in said bearing is a shaft 7',

the upper end of which is bent into a hand H crank is, thus affording a suspension means for said shaft and therethrough for the water wheel or paddle blades, and convenient durable means for turning said shaft.

The water wheel or paddle blade structure comprises a plurality of fiatstrips diverging from ad acent their point of connection with the shaft 1'. -I preferably em ploy ten such blades and assemble them about the lower end of the shaft 7' (which is squared to receive them) in the followin manner: The side sections are provided wit a flat central portion m-'n and outwardly extended arms m' n at each end of said fiat portion. The middle sections 0-p are of substantially straight stock, the inner ends thereof being spaced apart and being undercut at the inner end; the intermediate blades q'rs.-t having short end sections qrst' parallel with the portions M and inner ends of the sections op, and spaced apart to the sameextent, and under cut in the same manner as, the ends of said sections op, thus forming a rectangular hole for the end of the shaft j and a socket within which the end of said shaft may be upset to secure saidblades firmly thereupon, having no projection below same.

The outer ends of the sections qrst diverge from thesections op as shown in Figs. 2 and 3. Thexvarious sections m to 2) form of a vortex within the tank.

"the squared end of the shaft 3' preventing displacement of said sections.

The operation of the herein described machine is substantially as follows: When it is desired to wash dishes, the soiled dishes are placed upon the reticulated support '12. in any desired position and when the desired number of dishes have been placed in the machine, the free end of theflexible tube 6 is forced over the nozzle of a hot water faucet and water is run into the tank through the port a and nipple a until it has reached a level of about two thirds of the height of tank." The soap or washing powder having been mixed with this water, the'cr'ank handle is is slowly turned. It will be observed that the reticulated su-ppoi'tk, the bottom. bar d, and the cross bars g-g' will sustain the load of the dishes in a manner to prevent the said support sagging so as to come into engagement with the various paddle blades. Furthermore, the shaft. 9' will maintain these blades in position intermediate the bottom bar d and the bottom of the tank a, affording the proper clearance above and below said blades to avoid contact thereof with either of these parts. As theshaft j is turned by the handle'lc, the vertical surfaces of the various blades m to t will impart a swirling action to the mass of water within the tank, but will have no tendency to force it upwardly excepting that upward movement incidental to the As the water is thus moved around in a circle it will freely circulate between and about every portion of each dish and thoroughly cleanse same. I have found in 'practice that small mouthed pitchers and bottles may be as readily cleaned as flat dishes or cups or howls. I have also demonstrated that by turning the handle slowly for about two minutes all of the dishes which can be piled within the tank a and below the normal surface of the water may be readilycleaned. Care must be taken, however, not to turn the shaft 7' too rapidly as in case of too great a velocity in the water, there is a. tendency to move the various dishes and thus chip or break same. When the dishes have been thoroughly cleansed the tube b is removed After the dishes have been cleaned the frame may be readily removed from the tank, carrying with it the reticulated support and the paddle blades, thus permitting the thorough rinsing of all parts of the tank a as Well as of the mechanism removed.

It is not my intention to limit the invention to the precise details of construction, it

being apparent that such may be varied without departing from the spirit and scope of the invention.

Having described the invention what I claim as new and desire to have protected by Letters Patent is 1. A dish washing machineembodying therein a tank for the washing fluid, a rigid frame having a top bar extending across and engaging the edge of said tank, whereby said frame may be removably mounted in said tank, and a bottom bar adjacent the bottom of said tank, a rotatable shaft mount-' ed in said top and bottom bars, a plurality of paddle blades carried by said shaft, means whereby said shaft is supported to position said blades adjacent. but out of contact with, the bottom of said tank, said paddle blades having vertically disposed bucket surfaces whereby the cleaning fluid will be swirled about the tank, and a reticulated support for dishes mounted. upon said frame above said paddle blades,
